Pittsburgh Ballet Theatre will premiere a new work set to the music of Cole Porter and perform Bournonville's classic La Sylphide for the first time in 2005-06, the company announced.

The yet-to-be-named Porter ballet is the creation of Derek Deane, whose ballet set to Paul Simon songs premieres in Pittsburgh next month. It will be paired with the local premiere of Twyla Tharp's Nine Sinatra Songs.

The PBT will also give the first Pittsburgh performances of Amaedeo Amodio's Carmen, set backstage at a performance of the Bizet opera. The music, drawn from the opera, is arranged by Giuseppe Cali.

Also on the schedule are artistic director Terrence Orr's 2002 version of The Nutcracker, Saint-Leon's Coppelia, and Pas de Deux Perfection, a series of classic excerpts which will be paired with La Sylphide.
